Good grief, Charlie Brown! Those are some of the worst stocks of the year! Lucy probably got Apple and Facebook.

It's trick or treat time ... Wall Street style!

I usually use Halloween as an excuse to take a look at the year's best and worst stocks. I already wrote about Keurig Green Mountain (GMCR) on Thursday. It's a treat if you have it in your portfolio.

Consumers may still be hellbent for leather ... but they're buying it elsewhere. Competition from Michael Kors (KORS) and Kate Spade (KATE) has been brutal. Their stocks have taken a tumble this year too, but Coach has been hit the hardest.

3. The misfit toy stock. Sorry to any fans of Scandinavian group Aqua, but we're not living in a Barbie world anymore.

Mattel (MAT) shares have plunged this year along with Barbie sales. But it's not as if parents have stopped buying toys for their kids. Shares of Hasbro (HAS) are near an all-time high. Simply put, Hasbro has cooler toys that boys and girls want: NERF, My Little Pony, Star Wars and Transformers.

And it's going to get worse for Mattel (and better for Hasbro) soon. Mattel, currently the rights owner for toys tied to Disney's (DIS) Princess line of characters, is losing that deal to Hasbro in 2016 ... and that includes Elsa and Anna from "Frozen." Investors that haven't already done so may want to let Mattel go.

4. Rotten produce. Eating organic food is good for you. Investing in the company that made it popular for the masses? Not so much. Whole Foods (WFM) is a classic victim of its own success.

The stock has tumbled following numerous sales and earnings warnings. And the culprit is competition from more mainstream retailers like Kroger (KR) and Wal-Mart (WMT).

Whole Foods has acknowledged that it has to worry more about other retailers selling kale and quinoa for lower prices.

5. Put down the corporate credit card, Jeff! Amazon (AMZN) is a company that could be doing better. But CEO Jeff Bezos has chosen to sacrifice current profits in order to build for the future.

It's a strategy that has worked in the past. But investors are nervous that Bezos may be losing his Midas touch. The Fire Phone has been a failure. And losses are mounting as the company invests heavily in its cloud business.

Add in the fact that Amazon issued a less-than-stellar sales outlook for the fourth quarter and it's no wonder that the stock is one of the worst performers in CNNMoney's Tech 30 index this year.

Now it's worth noting that this year's tricks could be next year's treats. Edwards Lifesciences (EW), Intuitive Surgical (ISRG) and CenturyLink (CTL) have all bounced back sharply this year after a lousy 2013. But you have to do your homework.

Diamond Offshore was a loser last year. And last year's biggest S&P 500 laggard, Newmont Mining (NEM) is down again in 2014. Some dogs remain pooches.

So if QE is the egg, then are rate hikes the chicken? Because the egg came first, right? Or is it the other way around? Oh no.

Anyway, happy Halloween. Happy end of October. Here's hoping next month is less stormy for stocks. We don't want any cold November rain. Yup. I'm going there. Enjoy the next nine minutes of cheesy power ballad rock at its finest.

Best Buy, Citi, Avon and Yahoo are hot stocks. They named new CEOs in 2012. Coincidence? Or do investors love turnarounds?
